<h4>The project began with Eva's 102-year-old grandfather and his expensive hearing aids, which he can’t
operate himself. The feedback screeches unbearable noise into his ears, and the only
way to turn them off and on is to take out the batteries.. And the batteries don’t last long.</h4>
</div>
<p>So we gave him an old field recorder microphone with wired earbuds, a piece of professional audio
equipment which costs under €100. We turned on dynamic range compression and volume limiting.
His hearing improved immediately, and most of the time the setup can be turned on with a flick of a
switch. Even these basic DSP effects improved upon the medical state of the art.
We realised how badly the hearing technology space needs reform, and that modern audio
knowledge has long outpaced it.</p>

<h2>A large market that is still constrained by old product assumptions.</h2>
</div>
<p class="section-copy">The hearing aid industry is estimated at roughly USD 9.8 billion, but the broader accessibility opportunity is larger because many people who need hearing support never enter the formal hearing-aid market at all. A software-first model can reach them earlier, more affordably, and through devices they already use.</p>
</div>
<div class="opportunity-cards">
<article class="mini-card">
<h3>Business model options</h3>
<p>Premium desktop software, one-time pro licensing, DSP licensing for platforms, and hardware partnerships for accessible listening products.</p>
</article>
<article class="mini-card">
<h3>Distribution advantage</h3>
<p>Scale through existing computers and consumer devices before adding manufacturing complexity.</p>
